Abstract

This study takes 10 cities in Huaihai economic zone from 2014 to 2023 as the research object, and reveals the internal mechanism and dynamic process of land spatial efficiency by quantitatively analyzing the spatial evolution characteristics of land spatial efficiency. The study uses a multi-dimensional index system and entropy method to measure the level of land spatial efficiency in Huaihai Economic Zone, and analyzes the development differences and evolution paths among cities. The results show that the land spatial efficiency of Huaihai Economic Zone presents the obvious spatial distribution characteristics of "low in the middle and high around", and shows a fluctuating upward trend in time. Through spatial analysis and efficiency measurement, the study puts forward policy suggestions such as optimizing regional coordinated development, promoting ecological civilization construction, optimizing land use structure and spatial layout, which provides a theoretical basis and policy suggestions for the sustainable development of Huaihai economic zone.
